What type of interstate is designated for routes with 1 to 2 digits?

• A. Connectors to road
• B. Major interstate
• C. Interstate connectors
• D. Minor interstate

Answer: (B)

The designation of interstate routes with 1 to 2 digits typically refers to major interstate highways. These highways are primary routes in the interstate system, designed to facilitate long-distance travel and freight movement across states. The numbering system indicates their importance, where single-digit interstates (like I-5 or I-10) are among the most significant and connect major urban areas and regions. Major interstates are strategically located to form the backbone of the national highway system, directly linking major cities and states. They usually feature higher speed limits, fewer intersections, and are constructed to accommodate large volumes of traffic, contributing to their designation as major routes. Other types of interstate routes, such as connectors, are generally designated with three-digit numbers and serve to link the major interstates with local highways or access points. This distinction underscores the primary role that major interstates play in national transportation.
